Run Windows Memory Diagnostic or MemTest86 to check for faulty RAM and replace defective sticks if found. 2. Update or roll back outdated, corrupt, or incompatible drivers—especially for storage, graphics, and network devices—using Device Manager and official sources. 3. Repair corrupted system files by running sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth in an elevated Command Prompt. 4. Check disk integrity using chkdsk C: /f /r and assess SSD health with tools like CrystalDiskInfo, replacing the drive if failing. 5. Uninstall recently installed software or Windows updates that may be causing conflicts, particularly security, virtualization, or disk tools. 6. Disable overclocking settings including XMP/DOCP in BIOS/UEFI to eliminate instability from aggressive performance tuning. 7. Perform a full malware scan using Windows Defender or Malwarebytes to rule out malicious software affecting kernel memory. 8. Analyze minidump files in C:\Windows\Minidump\ using BlueScreenView or WinDbg to identify the faulting driver if the issue persists. The PAGE_FAULT_IN_NONPAGED_AREA error is typically resolved by addressing RAM issues or problematic drivers, and following these steps systematically usually fixes the problem.

The PAGE_FAULT_IN_NONPAGED_AREA Blue Screen of Death (BSoD) in Windows usually points to a critical system error where the OS tries to access data that should be in memory (RAM), but it's missing or corrupted — specifically in a part of memory that shouldn't be paged out to disk. While it can be alarming, it’s often fixable with methodical troubleshooting.

Here’s how to fix it:

1. Check for Faulty RAM

Memory issues are one of the most common causes of this BSoD.

• Run Windows Memory Diagnostic:

  1. Press Win R, type mdsched.exe, and press Enter.
  2. Choose "Restart now and check for problems."
  3. After reboot, the tool will test your RAM and report any errors.

• Use MemTest86 for a deeper test:

  
  • Download MemTest86, create a bootable USB, and run an extended test (4 passes).
  • If errors appear, one or more RAM sticks are faulty — try removing/replacing them.

Tip: If you recently added new RAM, remove it temporarily to see if the issue stops.

2. Update or Roll Back Drivers

Outdated, corrupt, or incompatible drivers — especially for storage, graphics, or network — can trigger this error.

• Update drivers:

  • Go to Device Manager (devmgmt.msc).
  • Look for devices with a yellow warning icon.
  • Right-click and Update driver.
  • Focus on: Disk drives, Display adapters, Network adapters, and System devices.

• Roll back problematic drivers:

  • If the crash started after a driver update, right-click the device → Properties → Driver tab → Roll Back Driver.

• Use trusted sources:

  • Avoid third-party driver updaters. Download drivers directly from your PC manufacturer or component vendor (Intel, NVIDIA, AMD, etc.).

3. Scan for Corrupted System Files

Windows system file corruption can lead to memory access issues.

Run these commands in an elevated Command Prompt (run as Administrator):

sfc /scannow

After it finishes, run:

DISM /Online /Cleanup-Image /RestoreHealth

• These tools repair the Windows image and replace corrupted system files.
• Restart your PC after completion.

4. Check Your Hard Drive or SSD

Disk errors can corrupt data that the system expects to be available in memory.

• Run CHKDSK:

  1. Open Command Prompt as Admin.
  2. Type:

     chkdsk C: /f /r

     (Replace C: if your OS is on another drive.)

  3. Press Y to schedule the scan on next reboot.
  4. Restart your PC — the scan may take a while.

  5. Check SSD health:

     • Use tools like CrystalDiskInfo to check drive health and SMART status.
     • If the drive is failing, back up data immediately and consider replacement.

  5. Uninstall Recent Software or Updates

  Sometimes, third-party software (especially antivirus, virtualization, or disk utilities) can interfere with kernel memory.

  • Uninstall recent programs:

    • Go to Settings > Apps > Installed apps.
    • Remove anything installed just before the crashes started.

  • Uninstall recent Windows Updates:

    • Go to Settings > Windows Update > Update history > Uninstall updates.
    • Remove recent quality or feature updates if the issue began after an update.

  6. Disable or Remove Overclocking

  Overclocked RAM, CPU, or GPU can cause memory instability.

  • Enter BIOS/UEFI and reset to default settings.
  • Disable XMP/DOCP profiles temporarily to test stability.
  • If the crashes stop, gradually re-enable settings while testing.

  ---

  7. Check for Malware

  Rarely, malware can corrupt kernel memory structures.

  • Run a full scan with Windows Defender or a trusted antivirus.
  • Use Malwarebytes for a second opinion.

  8. Analyze the Minidump File (Advanced)

  If the problem persists, analyze the crash dump:

  • Minidump files are located in C:\Windows\Minidump\.
  • Use BlueScreenView (free) or WinDbg (from Microsoft) to open the .dmp file.
  • Look for the faulting driver or module — it’s often listed near the top.
  • Once identified, update or remove that specific driver.

  ---

  Bottom line: Start with RAM and drivers — they’re the usual suspects. Work through each step methodically. The error often resolves after fixing memory issues or rolling back a bad driver.

  Basically, it’s not always hardware — but you should rule it out early.
